Uniformity-based large-particle-size asphalt mixture design method
The invention relates to the technical field of highway engineering, in particular to a large-particle-size asphalt mixture design method based on uniformity, which comprises the following steps: designing synthetic gradation composed of different particle sizes, evaluating the uniformity of the designed asphalt mixture by utilizing a small asphalt mixture distributor in combination with an extraction test, and selecting the gradation with the best uniformity as a target mix proportion. According to the method disclosed by the invention, the uniformity of the large-particle-size asphalt mixture is improved, the capability of maintaining the uniformity of the mixture in the paving process is ensured, and the engineering quality problem caused by aggregate segregation is reduced.
本发明涉及公路工程技术领域，尤其是一种基于均匀性的大粒径沥青混合料设计方法，设计不同粒径组成的合成级配，利用沥青混合料小型分料器结合抽提试验，评价所设计的沥青混合料的均匀性，选择均匀性最好的级配做为目标配合比，并验证其相应路用性能，本发明增加大粒径沥青混合料的均匀性，确保其在摊铺过程时保持混合料均匀性的能力，减少集料离析带来的工程质量问题。
